The early Edison films are what the Lumière Brothers called actualités:
unstructured footage of events and places.
Some provide a wonderful window into their time.
Later films are somewhat longer, many documenting special events like
parades and presidential visits.
For me, the most interesting is A Trip Down Market Street Before the Fire,
filmed just days before the 1906 earthquake and fire.
A companion piece filmed after the fire resurfaced in 2018,
but it is not yet available online.

The list below is roughly chronological; some dates are approximate.
Clicking on a title will play the film directly if your browser supports .mp4 streaming;
the info pages include other playback options as well as very detailed descriptions.
Timings include added head/tail credits.
The films and info pages are hosted at the Library of Congress.
The total running time for all the films is a little over two hours.
